AUTOMATIC WATER-CUT-OFF SPOUT.

SPECIFICATION forming part of Letters Patent No 769,314, dated September6, 1904. Application filed February 25,1904. Serial No. 195,804. (Nomodel.)

T (ZZZ whom, it nary concern: I

Be it known that I, J ETHRO MOORE HILL, a citizen of the United States,residing at Marissa, in the county of St. Clair and State of Illinois,have invented an Improved Automatic Water-Out-Off Spout and Filter, ofwhich the following is a specification.

This invention relates to a combined automatic cut-off spout and filter,and has for its object to provide a simple, inexpensive, and efficientdevice of this character which will discharge the flow of water from theroof of a building or other structure during a light rainfall andautomatically divert the increased volume of water through a filter intoa suitable tank or cistern during a heavy fall of rain.

A further object of the invention is to provide a water-chamber in whichis mounted a suitable float, said float being adapted to automaticallytilt the spout when the water in said chamber has reached apredetermined height and to automatically return the spout to its normalposition when the water recedes.

Astill further object is to provide the cut-off spout with a dripopening or orifice through which the water is discharged into thefloatchamber and, further, to provide a combined slide-valve anddeflector by means of which the size of the discharge-opening maybeincreased or diminished.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended, itbeing understood that various changes in form, proportions, and minordetails of construction may be resorted to without departing from theprinciple or sacrificing any of the advantages of this invention.

In the accompanying drawings, forming a part of this specification,Figure 1 is alongitudinal sectional view of a combined cut-off spout andfilter constructed in accordance with my invention. Fig. 2 is a top planview of the same. Fig. 3 is a detail perspective view of the spoutdetached.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In carrying out the invention I provide abox or casing 5, to the innerwalls of which are secured 1n any sultable manner stramers 6 and 7, thespace between the strainers 6 and 7 being filled with charcoal or othersuitable filtering material 8. The box-or casing 5 is designed to besupported in any suitable manner at a point adjacent the down-spout ofthe ment a float or buoy 12. The stem 13 of the float or buoy isvprovided with a terminal crank-arm 14, to which is pivoted the cut oflspout 15, so that as the water rises in the chamber 11 the spout will betilted to deliver the water from the down-spout into the filter,

and when the water in said chamber recedes the float will automaticallyreturn the spout to its normal position. The cut-off spout 15 isprovided with a drip-opening or orifice 16, through Which water isadmitted to the chamber 11, the size of said opening, and consequentlythe volume of water flowing therethrough, being regulated at will by avalve 17, slidably mounted in suitable guides 18,

secured to the spout, as shown. The rear end of the slide-valve 17 isbent upwardly to form a curved deflector 19, theobject of which is todeflect the water to each side of the opening 16 during a lightrainfall. By means of the deflector'19the water from the roof, which isusually contaminated with dust, leaves, and

other foreign matter at the beginning of a rain, is discharged at theend'of the cut-off spout without affecting the float 12.

Secured to the bottom of the spout 15 are a pair of oppositely-disposedperforated ears or lugs 20, and pivoted in the perforations of said lugsis a supporting-bail 21, the ends of which are bent inwardly, asindicated at 22, and engage suitable openings in the side walls of thechamber'll, as shown. A similar bail 23 is pivotedin perforated ears orlugs 24, secured to the rear end of the spout, the terminal portions ofsaid bail being bent outwardly and journaled' in the side walls of thebox or casing 5.

The distance between the upper pivotal connections of the bails 21 and23 is less than that of the lower pivotal connection, so as to changethe center of the cut-off spout on being reversed and give the downwardend thereof a preponderance in weight, said bails being so disposed withrespect to each other that when one bail is in a substantially verticalposition the opposite bail will be at right angles thereto, as shown.

As a means for permitting the gradual escape of water from the chamber11 Iprovide the lower end thereof with a threaded pipe 25, the cap 25 ofwhich is formed with a central opening or perforation through which thewater escapes, thereby causing the float to drop and automaticallyreturn the cut-off spout to its normal position when the heavy fall ofrain ceases.

From the foregoing description the construction of the device will bereadily understood,and the operation thereof may be briefly stated asfollows: The cut-off spout being in the position shown in Fig. 1 of thedrawings, water entering the spout during a light rainfall will bedeflected to the right and left of the drip-opening 16 and discharged atthe end of said spout. When the volume of water from the roof isincreased by reason of a heavy fall of rain, the water will flow overthe deflector and part of the same pass through the drip-opening 16 intothe chamber 11, thereby causing the float to rise and automaticallyreverse the position of the spout, in which position the water will flowinto the filter and thence to the tank or cistern. When the rain ceases.the water in the chamber 11 will gradually flow out through the orificein the cap 25, thereby permitting the float to drop and return thecut-oif spout to its normal position.

Having thus described the invention, what is claimed is 1. In adevice ofthe class described, the com bination with a box or casing, of a filter,a water-chamber, a float disposed within said chamber, a pivotedcut-ofl' spout having a dripopening in one end thereof forming a sourceof communication between the spout and water-chamber, and a valveslidably mounted above said drip-opening and having one end thereof bentupwardly to form a deflector, said spout being actuated by the float toreverse the position of the same.

2. In a device of the class described, the combination with a box orcasing, of a filter, a water-chamber forming a part of said box, a

float disposed within the chamber, a cut-off spout pivoted to the box orcasing and having a drip-opening formed in one end thereof, guidessecured to the spout on each side of the drip-opening, and a valveslidably mounted in said guide and having one end thereof bent upwardlyto form a deflector, said spout being actuated by the float to reversethe position of the same.

3. In a device of the class described, the combination with a box orcasing, of a lilter, a cut-off spout pivoted to the box and having adrip-opening formed in one end thereof,guidcs secured to the spout oneach side of said dripopening, a valve slidably mounted in said guides,a water-chamber, and a float arranged within said chamber for reversingthe position of the spout, there being a vent formed in the walls ofsaid chamber to permit the escape of water therefrom.

a. In a device of the class described, the combination with a box orcasing, a partition dividing said box into two compartments, a lilterarranged within one of said compartments, a float disposed within thesecond compartment, a cut-off spout pivoted to the box or casing andhaving a drip-opening formed therein and disposed above the secondcompartment, and a pivotal connection between the float and spout.

5. In a device of the class described, the combination with a box orcasing, of a iilter, a water-chamber, a float disposed within saidchamber, a cut-off spout provided with a dripopening, a pairof bailsforming a pivotal connection between the box and spout, and a pivotalconnection between said spout and float. i
